SPRINKLER.

SPECIFICATION forming part of Letters Patent No. 766,259, dated August 2, 1904. Application filed August 31,1903, Serial No. 171,366. \No model.)

To all 1071.01 it may concern:

Be it known that'l, LLOYD T.JARRARD, a citizen of the United States, residing at the city of Battlecreek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Sprinklers, of which the following is a specification.

This invention relates to improvements in sprinklers.

My improved sprinkler is particularly adapted for use as a lawn-sprinkler, although it is desirable for use in other relations.

The objects of this invention are. first, to provide an improved sprinkler which is comparatively simple in structure and positivein action by which a large area may be sprinkled and the water also evenly distributed; second, to provide an improved sprinkler which will operate satisfactorily under varying conditions of water-pressure; third, to provide an improved sprinkler which is economical to produce and durable and not likely to get out of repair.

Further objects and objects relating to structural details will definitely appear from the detailed description to follow.

The devices and means by which my inven tion is accomplished will appear in the following specification. The invention is pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanyingdrawings, forming a part of this specilication, in which---- Figure 1 is a plan view of my improved sprinkler. Fig. 2 is a detail vertical sectional view of the same, taken on line 2 of Fig. 1. Fig. 3 is a detail sectional view taken on line 3 3 of Fig. 2 through one of the delivery-ports a.

In the drawings the sectional views are taken looking in the direction of the little arrows at the ends of the section-lines, and similar letters of reference refer to similar parts throughout the several views.

Referring to the lettered parts of the drawings, A is the casing or head, having the chamber A within the same. A coupling member or tip A" is provided for the hose or supplypipe. The casing is supported on a suitable base or standard r The spray-wheel B, which is preferably formed of sheet metal, has a plurality of angularly-disposed l'lat blades B. The spraywhcel is supported on the centrally-arranged bearing-stem!) on the casingA. The wheel is secured in position by the set-screw B, which forms a journal therefor. (Jorrespomlingly arranged in a circle about the journal of the spray-wheel are a plurality of delivery passages or ports a.

The delivery passages or ports (1 are bored at an angle corresponding in general direction to the angle of the blades B and intersecting the same. (See Fig. 3). The delivery-ports 1/ are each adapted to deliver the wheel in the same relative relation, as clearly appears from the drawings. This causes a rapid revolution of the wheel, and the water is deflected by the same and thrown by centrifugal force over a large area. A portion of the water is delivered between the blades by the jets and falls within the main circle of water delivered by the centrifugal action due to the rotation of the spray-wheel, and thus evenly distributes the water over the whole circle. Thus arranged there is no liability of the wheel becoming balanced that is, the force of a portion of the jets from the ports offsetting the force of the remainderand thus stopping the revolution of the wheel or causing such friction on its bearing as to stop its revolution. The water is delivered through the ports a from the chamber A at a comparatively even pressure from each port.

Although comparatively small in size, my improved sprayer is adapted to spray a large area. The water is broken up by its contact with the wheel and the centrifugal force thereof, so that it is quite evenly distributed over the entire area.

I have illustrated and described my improved sprayer in detail in the form preferred by me on account of its simplicity of structure. Other changes in structural details will, however, readily appear to those skilled in the art to which my invention relates.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a sprayer, the combination of a casing having a chamber A therein; a centrally-arranged bearing-stem 7) on said casing; a wheel B having angularly-disposed flat blades B thereon, secured to said stem by the screw B which serves as a journal therefor; and a plurality of delivery-ports (z for said chamber A correspondingly arranged in a circle about the journal of said wheel, adapted to deliver at an angle having the same general direction as the angle of said fans or blades B and intersecting the same at such an angle as to secure a partial delivery between the blades of the wheel, for the purpose specified.

2. In a sprayer, the combination of a casing having a chamber A therein; a centrally-arranged bearing-stemfi on said casing; a wheel B having angularlydisposed flat blades B thereon, secured to said stem by the screw B which serves as a journal therefor; and a plurality of delivery-ports a for said chamber A correspondingly arranged about the journal of said wheel, adapted to deliver at an angle having the same general direction as the angle of said fans or blades B and intersecting the same at such an angle as to secure a partial delivery between the blades of the wheel, for the purpose specified.

3. In a sprayer, the combination of a casing having a chamber therein; a horizontally-archamber, correspondingly arranged in a circle about the journal for said wheel, adapted to deliver jets at an angle having the same gen' eral angle as the angle of said blades and intersecting the same at such an angle as to secure a partial delivery between the blades of the wheel, for the purpose specified.

4. In a sprayer, the combination of a casing having a chamber therein; a horizontally-an ranged wheel having angularly disposed blades supported on a suitable journal; a plurality of delivery passages or ports for said chamber, correspondingly arranged about the journal for said wheel, adapted to deliver jets at an angle having the same general angle as the angle of said blades and intersecting the same at such an angle as to secure a partial delivery between the blades of the wheel, for the purpose specified.

In witness whereof I have hereunto set my hand and seal in the presence of two witnesses.
